8 Claims. (Cl. 99--2) ABSTRACT OF THE DISCLOSURE OR 0 CH3 ii-o-dn-mrnn W \C=O 110- Where R is selected from the group consisting of hydrogen, benzyl and lower alkyl, and Z is selected from the group:

HO OH H er H H O substituted or unsubstituted alkyl, as methyl, ethyl, hexyl, etc. or

present invention can be produced from the compound:

CH=CH'(CH2)3 hereinafter referred to as the fermentation estrogenic substance (F.-E.S.) by the Diels-Alder reaction. The hydroxyl groups can be converted to ethers, e.g. methyl ethers, as taught in US. Patent 3,239,342. Benzyl ethers of PBS. are described in copending application Ser. No. 532,113, filed Mar. 7, 1966, now abandoned, and application Ser. No. 620,259, filed Mar. 3, 1967. and animal feeds containing growth promoting amounts thereof.

The compounds can be administered to animals by any suitable method including oral and parenteral administrations. For example, the compound can be blended with ordinary feed containing nutritional values in an amount sufiicient to produce the desired rate of growth and can thus be fed directly to the animals, or the compound can be suspended in a suitable injection suspension medium such as peanut oil and injected parenterally. The amount of compound fed to an animal, of course, varies depending upon the animal, desired rate of growth and the like.

When the new compounds are to be administered in feeds, an animal feed composition may be prepared containing the usual nutritionally-balanced quantities of carbohydrates, proteins, vitamins and minerals, together with the compound of the present invention. Some of these usual dietary elements are grains, such as ground grain and grain by-products; animal protein substances, such as those found in fish meal and meat scraps, vegetable proteins like soybean oil meal or peanut oil meal; vitaminaceous materials, e.g. vitamin A and D mixtures; riboflavin supplements and other vitamin B complex members; and bone meal and limestone to provide minerals. A type of conventional feed material for use with cattle includes alfalfa hay and ground corn cobs together with supplementary vitaminaceous substances if desired.

The following examples serve to illustrate the invention.

Example I F.E.S (0.1 mole) is gradually added to 0.1 mole (9.8 grams) of a well cooled suspension of maleic anhydride in 60 ml. of benzene. The mixture is warmed to about 60 C. and then held for several hours. The benzene is evaporated off and the product crystallized from methanol to yield:

Example II F.E.S. 2,4-dimethylether and F.E.S. 4-benzylether are reacted according to the procedure of Example I to produce the corresponding F.E.S. ether compound.

3 Example III Contact a 0.1 mol of F.E.S. dissolved in 500 ml. of ethyl'ether with S under a pressure of l to 100 p.s.i.g. at room temperature for a period of one to three weeks. Sulfur dioxide adds to the PBS. as indicated below:

The product is obtained in about a 70 percent yield and is separated from starting F.E.S. by column chromatography.

Example IV p-Benzoquionone (10.8 grams or 0.1 mole) is reacted with 0.1 mole of RES. in the presence of about 0.01 mole of acetic acid. The flask is cooled with water initially and then allowed to stand at room temperature for 48 hours. The adduct shown below is separated from starting F.E.S. by crystallization:

The adduct is then isomerized by heating with a small amount of HCl and SnCl for 15 minutes to give the final product:

HO-- OH Example V 1,4-naphthoquinone (15.8 grams or 0.1 mole) is reacted with 0.1 mole RES. in the presence of about 0.01 mole of acetic acid. The flask is cooled with water initially and then allowed to stand at room temperature for 48 hours. The adduct shown below is separated from starting F.E.S. 'by crystallization:

The adduct is then isomerized by heating with a small amount of HCl and SnCl for 15 minutes to give the final product:

HO OH Example VI Nitroethylene (0.1 mole or 7.3 grams) is reacted with F.E.S. (0.1 mole) dissolved in 500 ml. of ether at a temperature of 20 C., for several days. The ether and unreacted nitroethylene are removed by distillation and the product purified by distillation. The yield of product is 60 percent.

Example VII Acrolein (0.1 mole or 5.6 grams) is added to 0.1 mole of PBS. dissolved in 500 ml. of ether to which has been added a small amount of acetic acid (0.2 gram). The mixture is held at 25 C., for 72 hours after which the ether and acrolein are separated by distillation. The purified product is obtained by crystallization in a yield of 55 percent.

This product may be reduced by H over palladium charcoal to give:

Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example I per pounds of ration and their rate of growth is improved.

Example IX Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example II per 100 pounds of ration and their rate of growth is improved.

Example X Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example III per 100 pounds of ration and their rate of growth is improved.

Example XI Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example IV per 100 pounds of ration and their rate of growth is improved.

Example XII Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example V per 100 pounds of ration and their rate of growth is improved.

Example XIII Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compounds of Example VI per 100 pounds of ration and their rate of growth is improved.

Example XIV Six head of cattle are fed a daily ration of alfalfa hay and ground corn cobs containing 1 to 20 grams of the compound of Example VII per 100 pounds of ration and their rate of growth is improved.

The following are specific examples of animal feed compositions of this invention useful for increasing the rate of growth and feed efliciency of young animals to market weight.

Example XV For young beef cattle, i.e., calves to yearlings running to two year olds, each animal is given 5 to 20 milligrams per day of the compound produced in Example I intimately admixed in about 18 to 22 pounds per head per day of a complete pelleted ration for about days. The complete pelleted ration includes in addition to the compound of Example I the following:

Grams/ton: Mg./head/day .5 5 1.0 10 2.0 20 4.0 40 8 80 These gram amounts are premixed with, for example, 10 pounds of soybean hulls prior to admixture with the other ingredients.

Example XVI For young swine, i.e., six week old pigs to about 100 pound pigs, each animal is given to 20 milligrams per day of the compound of Example III intimately admixed in about 1 /2 to 5% pounds per head per day of a grower ration until it reaches a weight of about 100 pounds. When the swine weight between 90 and 125 pounds the feed is changed to one whereby each animal is given 20 to 50 milligrams per day of the compound of Example III intimately admixed in about 5 /2 to pounds per head per day of a finisher ration until it reaches market weight of about 220 pounds. The grower and finisher ration include in addition to the compound of Example III the following:

Grower, Finisher, percent percent Ground Yellow Corn 77 86. 7 Soybean Meal (44% protein) l6 6. 5 Meat and Bone Scraps (50% rot 2. 5 2. 5 Dehydrate Alfalfa Meal (17%--- 2. 5 2. 5 Steamed Bone Meal 0. 5 0. 5 Ground Limestone 0. 6 0. 3 Iodized Salt 0. 5 0. 5 Vitamin, Antibiotic and Trace Mineral Premix 0.5 0.5

The compound of Example III is admixed with the above ingredients in a blender in the following amounts in milligrams per pound to provide an appropriate feed with dosage levels ranging from 6 to 96 milligrams per head per day.

Mg./pound: Mg./head/day 2 6 4 12 8 24 16 48 32 96 Example XVII For 4 to 10 month old lambs weighing 50 to 70 pounds, each animal is given 1 to milligrams per day of the compound of Example IV, intimately admixed in about 3 to 6 pounds per head per day of a complete ration for 30 to 90 days. The complete ration includes in addition to the compound of Example IV the following:

The compound of Example IV is admixed with the above ingredients in a blender in the following amounts in milligrams per pound to provide an appropriate complete feed with dosage levels ranging from 1 to 15 milligrams per head per day.

Mg./pound: Mg./head/day .5 2 1.0 4 1.5 6 2.0 8 2.5 10 3.75 15 Example XVIII For broilers, i.e., day old to four week old chicks, a grower feed is prepared for feeding to the chicks for the first four weeks and a finisher feed is prepared for feeding the four week old chicks for the last five weeks until they reach market weight of two and a half to three pounds dressed. For each pound of weight gain, the chicks eat about 1.5 to 2 pounds of feed. Thus they eat about 1.5 pounds of feed during the first four weeks and about five pounds of feed during the next five weeks. During the course of this feeding schedule, each bird should receive a total of about 12 to 36 milligrams of the compound of Example VI in the grower and finisher feed each of which includes in addition to the compound of Example VI the following:
